Clinically, cysts in most organs do not go away once they occur, but cysts in the breast may go away. If a cyst occurs in the thyroid, liver, kidney, pancreas or spleen, there is no medicine that can control the growth of the cyst to make it shrink or disappear, only close observation and regular follow-up, and surgery can be considered when the cyst increases in size or symptoms appear. Breast cysts are mostly seen in young and middle-aged women with cystic hyperplasia of the breast, which is caused by an imbalance of estrogen, progesterone and prolactin in the body. Conservative treatments are usually used, which means relaxing the mood, detoxifying the liver and regulating the qi, avoiding too oily, spicy and stimulating foods, and combining with traditional Chinese medicines, such as Easy Pill, if necessary, most of the patients can be relieved of the symptoms and cured without surgical treatment, and the symptoms will subside. The cysts will subside. So clinically, most cysts will not subside, but breast cysts can subside.
